Ever felt insignificant? If you have an understanding of what is presented in this image you should. Nearly every object in this image is a galaxy containing millions and in most cases billions of stars. The image is called the Hubble Ultra Deep Field and was taken in 1995 and 1998.
The objects in this image are extremely dim and not detectable by ground-based telescopes. Even the Hubble Space Telescope cameras had to collect light over 278 hours to produce this image. There are 10,000 galaxies in the image. Using this image it has been estimated that there are 130 billion galaxies in the Universe at least as bright as the dimmest galaxy in the image.
